Changing data aspects
The data for a Gantt chart is set up when you load and map data in the New Gantt Chart Wizard or open a template. The Designer lets you change the data loaded and the mapping for an existing chart.
If you have an existing chart and you want to include further data from the same data source, or try out a new data set, you can reconfigure the data associated with the chart.
You can change the following aspects of the data associated with the chart:
The data file
The data mapping
If you have changed the data file, you must define a new mapping. If you have the same data file, you can change the mapping anyway, for example, to load extra data.
This section reconfigures the data for the
harbor1 activity-oriented chart; see
Loading data from a database. It assumes that you have decided to make a new version of the chart that includes the dock and turnaround time, with the activities for the DRE dock displayed showing this time.
First choose File > Open and browse to select the harbor1.igpr project file.
Choose Data > Reconfigure Data. The Reconfigure Data Wizard opens at the Gantt Connect to JDBC Data Source page.
Data connection configuration
The displayed information reflects the current configuration.
To change the SQL query for activities to retrieve extra data:
1. Add Dock and TurnaroundTime to the columns to retrieve.
2. Click Execute Query to load the data and see the new column in the Preview.
The following figure shows the reconfiguring data: additional columns.

4. Click Next.
Data mapping
To make use of the extra data in your diagram, you need to map it. In this example, the properties Dock and TurnaroundTime have been automatically created and mapped to the Dock and TurnaroundTime columns.
